AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WAKEFIELD VA
410 PM EDT THU JUL 21 2011

.SYNOPSIS...
A BROAD AREA OF HIGH PRESSURE...WHICH STRETCHES FROM THE CENTRAL
PLAINS INTO THE WESTERN ATLANTIC...WILL REMAIN IN CONTROL OF THE
WEATHER THROUGH THE WEEKEND. THIS WILL BRING HOT AND HUMID
CONDITIONS TO THE AREA THROUGH SUNDAY. A COLD FRONT WILL BACKDOOR
INTO THE AREA SUNDAY NIGHT AND MONDAY...DROPPING TEMPERATURES.

&&

.NEAR TERM /THROUGH FRIDAY/...
THE UPPER RIDGE REMAINS IN PLACE ACROSS THE REGION THROUGH FRIDAY.
WITH THIS RIDGE...THE MOISTURE IS LIMITED TO MAINLY 800MB AND
BELOW. FROM 700 MB AND ABOVE IT IS VERY DRY. COMBINE THIS MOISTURE
PROFILE WITH 700 MB TEMPERATURES AROUND 10C AND ABOVE...AND CONVECTION
SHOULD REMAIN CAPPED DUE TO THE WARM AIR ALOFT AND THE DRY AIR
ENTRAINMENT. THE MODELS ARE IN VERY GOOD AGREEMENT THROUGH ABOUT
36 HRS...EXPECT THAT THE NAM DOES TRY TO INDICATE SOME ISOLATED
CONVECTION LATE FRIDAY IN THE SERN PART OF THE CWA...BUT TYPICALLY
WITH THIS TYPE OF RIDGE IT IS VERY DIFFICULT FOR CONVECTION TO
DEVELOP. AS A RESULT...WILL KEEP DRY CONDITIONS THROUGH THE
PERIOD. BUT THE LOW LEVELS DO REMAIN VERY HUMID WITH DEW POINTS IN
THE MID TO UPPER 70S. THIS COMBINED WITH THE HEAT...TEMPERATURES
IN THE LOWER 100S ARE EXPECTED BASED ON THE 850 MB TEMPS BETWEEN
23 TO 25 C...WILL PRODUCE DANGEROUS HEAT INDEX VALUES ON FRIDAY
AFTERNOON WITH VERY STICKY CONDITIONS TONIGHT...AS LOWS HANG IN
THE MID TO UPPER 70S. AT THIS POINT...SEE NO REASON TO CHANGE
HEADLINES AS TEMPS IN THE LOWER 100S WITH MID 70S DEW POINTS WILL
PRODUCE HEAT INDEX VALUES BETWEEN 110 AND 120.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
THE MODELS BEGIN TO SHOW SOME DIFFERENCES ON FRIDAY NIGHT INTO SATURDAY
AND CONTINUE TO DO SO INTO SUNDAY AS THE UPPER RIDGE SLOWLY SLIDES
EAST...BUT THE MODELS BEGIN TO STRUGGLE WITH CONVECTIVE FEED BACK
ISSUES. THE NAM STARTS TO PRODUCE LOTS OF CONVECTION ON SATURDAY
AFTERNOON...DESPITE THE DOME OF HOT AIR STILL SITUATED OVER THE
AREA. AT THIS POINT...NOT SEEING ANY KIND OF TRIGGER SO WITH THE
JUST THE DAYTIME HEATING THINKING THE NAM IS OVERDONE WITH THE
CONVECTION. THE GFS KEEPS THE DRY AIR IN PLACE AND LIMITS AND
CONVECTION TO THE MOUNTAINS WEST OF THE AREA. PERHAPS A STRAY
SHOWER COULD COME OFF THE MOUNTAINS AND IMPACT THE WESTERN PART OF
THE CWA...BUT OTHERWISE EXPECT ANOTHER HOT DRY DAY. AS A RESULT OF
THE DIFFERENCES OF THE NAM IS MUCH COOLER WITH THE TEMPS ON
SAT...BUT THAT SEEMS UNLIKELY SO HAVE GONE WITH THE HIGHER MAV
NUMBERS FOR NOT ONLY THE LOWS FRIDAY NIGHT BUT THROUGH THE DAY
SATURDAY AND SATURDAY NIGHT AS WELL. AS A RESULT...HAVE MAINTAINED
THE CURRENT HEADLINES THROUGH SATURDAY.

ON SATURDAY NIGHT INTO SUNDAY...THE GFS STARTS TO SHOW SOME
COMPLEXES OF STORMS ON SATURDAY NIGHT...BUT THAT SEEMS TOO QUICK
AS THE FRONT TO TRIGGER THE CONVECTION IS STILL TOO FAR NORTH.
EXPECT THAT IT WILL WAIT UNTIL SUNDAY AFTERNOON SO HAVE TARGETED
SUNDAY AFTERNOON FOR BETTER CHANCES OF SHOWERS. FOR
TEMPERATURES...HAVE GONE WITH THE MEX NUMBERS FOR NOW...BUT SHOULD
THE CLOUDS BE LESS...COULD SEE ONE LAST DAY OF HIGH TEMPS AND HEAT
INDEX VALUES...BUT WILL NOT EXTEND HEADLINES AT THIS POINT WITH
THE UNCERTAINTY OF THE CONVECTION.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
WENT WITH THE HPC GUIDANCE ON THE FRONTS. THIS IS SIMILAR TO A BLEND
OF GLOBAL ENSEMBLE GFS AND THE ECMWF. THIS WILL AT LEAST TEMPER THE
HEAT BY MONDAY AS A COLD FRONT APPROACHES FROM THE NW. THE MODELS
ARE NOT SURE HOW FAR SOUTH THIS FRONT GOES AND WENT WITH HPC AND
BRING IT TO NEAR THE NORTH CAROLINA VIRGINIA BORDER BY TUESDAY AND
THEN SLOWLY DISSIPATES ACROSS THAT AREA ON WEDNESDAY AND THURSDAY.
THERE WILL BE A LITTLE COOLING ALOFT WITH THE FRONT APPROACH AND
MORE CLOUDS WHICH SHOULD KEEP HIGHS CLOSER TO 90 AND LOWS FROM THE
UPPER 60S TO MID 70S. WITH THE FRONT BEING WEAK DO NOT EXPECT A LOT
OF ORGANIZED THUNDERSTORMS BUT SHOULD HAVE SOME AROUND MONDAY
THROUGH WEDNESDAY.

&&

.AVIATION /20Z THURSDAY THROUGH TUESDAY/...
HOT AND HZY VFR CONDS TODAY. SATELLITE SHOWS CU DEVELOPING BUT WARM
AIR ALOFT WILL INHIBIT ANY SIGNIFICANT LIFT FOR TSTMS. ONLY A
SLIGHT CHC FOR ANY TSTM DEVELOPMENT. WNDS S-SW 5-10 KTS AND
EXPECTED TO TURN SW-W OVERNIGHT. VIS 2-5 MI IN FOG/HZ OVERNIGHT.
SOME STRATUS COULD AFFECT EASTERN SHORE ESP ALONG THE COASTAL
AREAS. MORE HOT...HUMID AND HZY ON FRI AND SAT. STILL NO OBS FROM
SBY. FAA MAINTENANCE ISSUE. SO WILL CONT WITH AMD NOT SKED.

&&

.MARINE...
MODELS CONTINUE BERMUDA HIGH WITH A LEE SIDE TROF TO THE WEST. THIS
WILL KEEP WINDS SOUTH TO SOUTHWEST THROUGH SATURDAY. THE NAM TRIES
TO PUSH THE TROF A LITTLE FARTHER SE ON SATURDAY BUT LIKE THE GFS
KEEPING IT TO THE WEST AND KEEPING WINDS MORE WESTERLY. WITH ONE
WEAK FRONT APPROACHING ON SUNDAY THEN HAVE MORE NORTHERLY COMPONENT
LATE IN THE DAY BUT BY MONDAY WILL BE TURNING BACK TO THE EAST AND
THEN SOUTH BUT MONDAY NIGHT. THIS FOLLOWS GFS AND ECMWF AT THOSE
TIME FRAMES. WINDS ARE LIGHT THROUGH THE PERIOD. COULD SEE A LITTLE
INCREASE IN SWELLS FRIDAY AND SATURDAY AS BRET SLOWLY WEAKENS WELL
OFFSHORE.
